OPERATING HINTS
1. If Automatic controls appear to work backwards, ensure that the sensor potenĆ
tiometer shafts are in the correct orientation:
1. Front steering sensor: pot shaft faces rear of machine.
2. Rear steering sensor: pot shaft faces rear of machine.
3. Height sensor: pot shaft faces front of machine.
2. If entire mold does not fill with concrete, increase vibrator pot settings as reĆ
quired. Ensure that concrete level is maintained in the hopper at all times.
3. If curb surface quality is not acceptable, confirm concrete mixture or adjust viĆ
brators as required. Ensure that mold was cleaned after previous pour.
4. If concrete surface quality is not acceptable, check:
1. Use of proper concrete mix.
2. Proper concrete slump.
3. Proper mold angle.
4. Air escape slot at rear of mold must be clear.
5. Recommended concrete mixture:
1. Standard Slipform paver mixture:(for 1 cubic yard)
A. 50%-50% (about #1500 each) mixture of 3/4" rock and sand.
B. 550# of cement (6 bag mix).
C. 6% air entrainment on site.
2. 1-1/2" to 2-1/2" slump. Generally, the taller the form, the stiffer the mixture
must be. Low wide forms may be poured with a wetter mixture.
6. When not using automatic controls (sensors) turn Auto Power off.
7. While pouring a gradual radius, adjust front sensor horizontally to keep paver
from interfering with string line. Reposition the sensors after the string line
straightens out. Flip rear drive off while turning.
8. The position of the stringline determines the final alignment of the curb and gutĆ
ter. Therefore the position of the stringline must be consistent in relation to the
desired curb and gutter line. Keep stringline vertical and horizontal variations
within 1" of ideal for best results.
9. If machine will not drive, check the Rear Drive switches. If the side drive unit or
the optional right rear drive wheel is not used, flip the switch to the off position.
(See Assembly Instructions, page 18.)
10. If auto-height control does not appear to function correctly, ensure that the
Side Drive Unit switch is in the correct position. The Side Drive Unit switch transĆ
fers auto-height control between the center wheel and the side drive unit
wheel. When using the Side Drive Unit, flip the switch to attached. When not usĆ
ing the Side Drive Unit, flip the switch to detached.
